Specific embodiment
The utility model is described in more detail with reference to the accompanying drawing.
This one end of trapezoidal thread anchor head 3 becomes leading portion in Fig. 1.
As shown, one kind can apply prestressed complete anchor system, including anchor pole, it further includes self-locking device 9, spiral shell
Strainer 5, prestressing force implementing device are revolved, anchor pole includes sequentially connected trapezoidal thread anchor head 3, reducer 17 and anchor rod body 6, anchor
6 sets of club shaft in spiral strainer 5;Spiral strainer 5 is serrated along axial direction.
Anchor rod body 6 is equipped with body of rod protrusion 8, and the body of rod 8 leading portions of protrusion are set with self-locking device 9;Self-locking device 9 includes adding
Strong floor 12 and from lock barrel 13, the leading portion of body of rod protrusion 8 is sleeved on from lock barrel 13, is equipped with and reinforces from the bottom of lock barrel 13
Floor 12;The front end of anchor pole is equipped with prestressing force implementing device, and prestressing force implementing device includes work anchor 10, stress dispersion casing
11, jack 2 and positioning backing plate 4, are equipped with stress by trapezoidal thread on trapezoidal thread anchor head 3 and disperse casing 11,
The end sleeve of anchor rod body 6 loads onto positioning backing plate 4, work anchor 10 is fixed in positioning backing plate 4, in the front of work anchor 10
